Abstract

The utility model relates to a novel spring pulley device. The novel spring pulley device is used in a sliding door of a door or a window or a cabinet or other furniture. According to the novel spring pulley device, a supporting rod is arranged inside the front portion of a shell, a sliding rod is arranged inside the rear portion of the shell, one end of a pulley frame is hinged to the supporting rod, and a pulley is installed at the other end of the pulley frame; one end of a supporting frame is hinged to the middle section of the pulley frame, the left side face and the right side face of the other end of the supporting frame are correspondingly and respectively provided with an oblique oval hole, the supporting rod penetrates through the oval holes to support the end provided with the oval holes of the supporting frame, a spring is arranged between the rear side face of the supporting frame and the rear side face of the shell, an adjustment screw is arranged in the spring in a sleeved mode and penetrates through the rear side face of the shell, and one end of the adjustment screw is in contact with the rear side face of the supporting frame. The novel spring pulley device has the advantages that the structure is reasonable, the manufacturing cost is low, the novel spring pulley device can be adaptable to the working environment that barriers often exist in sliding grooves of sliding doors, the reset spring is effectively protected against damage, and the service life of the sliding doors is prolonged.

Description

A kind of novel spring pulley gear

Technical field

The utility model relates to a kind of novel spring pulley, specifically a kind of sliding-door pulley with back-moving spring.

Background technology

At door at home, window, wardrobe, in locker etc. furniture or door and window, it is a kind of easy to use using sliding door, the selection of simple and fast is installed, play critical effect and whether smooth and easy the pulley of sliding door while installing the in use size of noise and push-and-pull of sliding door, on market, businessmans can load onto spring and play damping effect on pulley, thereby reduce the noise while use, but sliding door is in some environments for use, in chute, be easy to exist bar, when a little, the holding capacity of spring is just tested, be damaged at the long-term elastic force that uses lower spring, thereby slide force smooth degree in the time of push-and-pull is declined.

Utility model content

The purpose of this utility model is to provide a kind of novel spring pulley gear, and it can adapt to usually exist in sliding door chute the working environment of bar, and effectively protects back-moving spring impaired, makes to push away to connect to improve an application life.

Technical solution of the present utility model is at shell, spring, adjustment screw, pulley, on the basis of pulley yoke, its feature has bracing frame, front is in the enclosure provided with a support bar, rear is in the enclosure provided with one and slides bar, and one end of pulley yoke is hinged on support bar, and its other end is provided with pulley; Described bracing frame one end and the interlude of pulley yoke are hinged, the arranged on left and right sides face of its other end with the sliding on the corresponding position of bar of shell, be provided with accordingly respectively the slotted eye of an inclination, support bar is being accepted this end of bracing frame through slotted eye, between the trailing flank of bracing frame and the trailing flank of shell, be provided with a spring, spring inner sleeve has an adjustment screw, and adjustment screw is through the trailing flank of shell, and its one end contacts with the trailing flank of bracing frame.

The operating principle of the new type of this practicality is under the cross support active force by pulley yoke and bracing frame; effectively alleviate the holding capacity of spring; an adjustment screw is set in the rear end of shell again; utilize the intubating length of adjustment screw; regulating spring ratio by compression easily; thereby carry out in the size that can easily drop to bar in sliding door slide slot according to environment for use the compression factor that regulating spring adapts to, when can making like this spring performance maximum cushioning effect, can protect again spring to damage spring itself because unexpected factor is subject to overweight compressive force.

The utility model has the advantages that rational in infrastructure, low cost of manufacture, it can adapt to usually exist in sliding door chute the working environment of bar, and effectively protects back-moving spring impaired, makes to push away to connect to improve in application life.
